Abstract

The configuration enables the introduction of a material web, which can be divided up into material sub-web strands, into the conveying paths of an angle-bar superstructure of a rotary printing machine. A slitting arrangement, which can be positioned in a variable manner in the angle-bar superstructure, and web drawing-in devices and components for attaching the material web or the material sub-web strands to the web drawing-in devices are provided. Assigned to the web-running plane is an adjustable advancement element which bridges a contact-pressure gap in relation to a mating roller, accommodated in the angle-bar superstructure, and by way of which one of the material sub-web strands or can be attached to an introduction element which can be moved into the web-running plane.

Claims

1. A configuration for introducing a material web into conveying paths of an angle-bar superstructure of a rotary printing machine, comprising:

a slitting arrangement variably positionable in an angle-bar superstructure of the rotary printing machine for selectively dividing the material web into a plurality of sub-web strands;

web drawing-in devices disposed downstream of said slitting arrangement in a web travel direction and components for attaching the material web or the material sub-web strands to said web drawing-in devices;

a mating roller disposed in the angle-bar superstructure and defining a web-running plane;

an adjustable advancement element disposed in the angle-bar superstructure for bridging a contact-pressure gap in relation to said mating roller, and configured to attach one of the material sub-web strands to an introduction element movably disposed into the web-running plane, said introduction element being attached to one of said web drawing-in devices in an inactive state an being movable into the web-running plane.

2. The configuration according to claim 1, which comprises a clamping device releasably retaining said introduction element above the web-running plane, in the angle-bar superstructure.

3. The configuration according to claim 1, wherein said introduction element is partially retained on a circumference of said advancement element.

4. The configuration according to claim 3, which comprises a carrier plate with contact-pressure wheels connected to said introduction element, and wherein said introduction element carries an adhesive strip and, during an attachment to a material sub-web strand, is guided by said contact-pressure wheels on said carrier plate and said advancement element.

5. The configuration according to claim 1, wherein the contact-pressure gap is bounded by peripheral surfaces of said advancement element and said mating roller.

6. The Configuration according to claim 1, wherein said advancement element extends substantially over half a width of an uncut material web.

7. The configuration according to claim 1, wherein said introduction element is one of a plurality of introduction elements, and said introduction elements, for introducing the material web or the material sub-web strands, include a coupling device.

8. The configuration according to claim 7, wherein said introduction elements carry adhesive strips along a base thereof, said strips extending in a direction perpendicular to the conveying direction.

9. In combination with a web-processing rotary printing machine, the configuration according to claim 1 for introducing a material web or material sub-web strands into conveying paths of an angle-bar superstructure of the rotary printing machine.
